Partial view is a reusable view (like a user control) which can be embedded inside other view.Once the partial view is created you can call the partial view in the main view using the Html.RenderPartial method.

Partial views are views without any design. These are used as user controls in MVC. We can create a partial view and used at more than one places in our application.
